Title: Anchor configuration
Inventor: NAKAMURA SOJIRO
IPC: B63B21/30
Filed: 1984-07-12
Abstract: PURPOSE:To obtain large holding power by forming an anchor in a body with the shank in such a manner that the right and left surfaces of its fluke are inclined obliquely afterward. CONSTITUTION:An anchor fluke constructed in a body with its shank is formed in such a manner that the right and left surfaces of its fluke are inclined obliquely afterward. Once the fluke is pierced into the sea floor, sufficient holding power is obtained since the inclined right and left surfaces of the fluke can secure its sufficient piercing preventing the anchor from slipping.

Title: Video signal converting device
Inventor: HONDA KOJI
IPC: H04N5/46
Filed: 1999-05-25
Abstract: PROBLEM TO BE SOLVED: To speedily identify whether or not an input video signal is a telecine- converted video signal by deciding whether or not the input video signal is the telecine-converted video signal on the basis of respective correlation values between an interpolation field and fields before and after one field period. SOLUTION: Field memories 1, 3 and 4 output input video signals after delaying them for one field period and line memories 2, 5 and 6 output the input video signals after delaying them for one horizontal period. A motion detector 8 detects the motion of an image and a scan line interpolator 9 performs scan line interpolating processing corresponding to detection outputs from a mode detector 7 and the motion detector 8. On the basis of video inputted signals S6-S3, S1 and S0, the mode detector 7 detects whether the input video signal is the telecine-converted video signal from a projection film or the video signal of a standard television system. Thus, the video signals of sequential scanning can be speedily generated from the video signals of interlaced scanning.

Title: Fuel assembly
Inventor: SANO HIROKI
IPC: G21C3/22
Filed: 1989-06-09
Abstract: PURPOSE:To prevent the inner tube from being exposed to vapor and to improve the durability by forming the inner tube of a spectral shift rod to a double tube structure whose gap is small enough and forming a triple structure together with the outer tube by the whole spectral shift rod. CONSTITUTION:The inner tube is formed by a double tube structure consisting of an upflow side inner tube 8a, a downflow side inner tube 8b and a gap 11 placed between both of them, and formed to a triple structure together with the outer tube 9. In an area of the upper part than the upflow water surface 4 and the downflow water surface 5, the wall surface of the upflow side of the inner tube 8a and the downflow side of the inner tube 8b is exposed to vapor. However, since a sufficiently narrow gap 11 exists between the inner tube 8a and 8b, water is sucked up from the upflow water surface by a capillary phenomenon, and by this water, heat is eliminated enough from the downflow side of the inner tube 8a and the upflow side of the inner tube 8b. Accordingly, it is possible to be fit for use of a longer period than before.

When no password is in existence, a NAK is sent and when in existence, the password is stored and whether or not the confidential box number and the image are in existence in the box is checked. When the condition above is not satisfied, the processing is terminated and when satisfied, the presence of the password is checked. When the password is not in existence, information of confidential image to be sent is set to a parameter without confirmation of the password.

Abstract: PURPOSE:To prevent the peeling of the film sticking to a shielding plate and to allow the formation of a uniform film on a semiconductor substrate by providing the shielding plate at the part exclusive of a route for particles from a supply source for the particles of the film to the semiconductor substrate. CONSTITUTION:The shielding plate 8 is provided around the semiconductor substrate 14 facing a target 5. Electric power is impressed to a heater 9 and the substrate is heated while the temp. of the shielding plate 8 is detected by a temp. sensor 10. The particles of W, etc., driven out of the target 5 arrive at the semiconductor substrate 14 and stick thereon, thus deposited thereon as the film. The particles stick to the circumferential shielding plate 8 as well. After the film of the prescribed thickness is formed on the substrate 14, a temp. controller 12 increases the electric power to be applied to the heater 9 to maintain the temp. of the shielding plate 8 at about 250 deg.C. The generation of the fatigue by the contraction and expansion in the film 5a sticking to the shielding plate 8 is obviated and the peeling of the film 5 is suppressed. As a result, the film having a uniform thickness is deposited on the semiconductor substrate 14.

Abstract: PURPOSE:To obtain picture information of a comparatively dark light source accurately by operating a horizontal shift register only by taking an interval of read operation as a chance to eliminate an electric charge of blooming and vertical smear component. CONSTITUTION:Pulses 21-22 are vertical scanning pulses at actual signal read and the next read is executed when a vertical trigger pulse goes to a high level, and only horizontal trigger pulses 24...25... are inputted till the next read and horizontal switch MOSs 5 only are conducted sequentially while keeping vertical MOSs 6 in cut-off state. The signal electric charge remains stored in a photodiode 7 with this operation and the electric charge for smear component and blooming component swept onto a vertical signal line 4 is read on a signal line 8. This smear component and blooming component are added to a memory provided separately from a memory for picture information, and since both the components are proportional to light quantity the light source is taken as a reference for the comparison of the lightness of light starts 10, 11.

Abstract: PURPOSE:To execute a quick and accurate inspection of an error detecting check code generator and an error detecting/correcting device, by using a static RAM provided together with a dynamic RAM. CONSTITUTION:A static RAM7 is provided together with a dynamic RAM6 for practical use. When a diagnosis command signal is delivered via a memory control part 5 for an error detecting check code generator 4, the RAM7 containing an address element works in response to a diagnosis writing command given from a control part 5. Then a memory read selector 22 selects the read output of the RAM7 via the part 5, and a malfunction of the generator 4 is inspected by an error detecting/correcting circuit 9. The circuit 9 is also inspected in the same way. As the RAM6 is not used for inspection, a preliminary inspection is not needed for a refresh circuit, a timing circuit, etc. This ensures a quick and accurate inspection of the generator 4 and the circuit 9.
